Image reading apparatus

An image reading apparatus comprising:

• a housing including:
• a first inlet;
• a second inlet disposed at a different position from the first inlet;
• and
• a switchback opening;
• a transport path extending substantially horizontally between the second inlet and the switchback opening;
• a reader disposed along the transport path and configured to read an image on a card;
• a sensor disposed adjacent to the second inlet;
• a transport unit configured to transport the card along the transport path;
• a positioning mechanism configured to move the reader between a first position and a second position;
• a motor configured to supply a drive force to the transport unit and the positioning mechanism;
• and
• a controller configured to:
• in response to the sensor detecting the card at the first inlet, activate the motor such that the transport unit transports the card via the reader toward the switchback opening in a first transport direction along the transport path;
• in response to an expiration of a first time period since activation of the motor, stop the motor and reactivate the motor such that the transport unit transports the card via the reader toward the second inlet in a second transport direction opposite to the first transport direction along the transport path;
• control the reader to read the image on the card while continuing to drive the motor for the transport unit to transport the card in the second transport direction;
• and
• in response to an expiration of the first time period since reactivation of the motor, stop the motor,
• wherein the positioning mechanism is further configured to:
• in response to the activation of the motor, move the reader from the first position to the second position by using the drive force from the motor;
• and
• in response to the reactivation of the motor, maintain the reader at the second position while the transport unit transports the card in the second transport direction until an entirety of the card has passed the reader in the second transport direction, and then move the reader from the second position to the first position by using the drive force from the motor.
